Open Type Thin Section Four Point Contact Ball Bearings (Type X)

Introduction

Open Type Thin Section Four Point Contact Ball Bearings (Type X) are also known as equal section thin section four point contact ball bearings because, unlike ordinary rolling bearings, the cross-section of thin section four point contact ball bearings of this series remains constant regardless of the size of the bearing bore.

The difference between thin section four point contact ball bearings (Type X) and thin section angular contact ball bearings (Type A) and thin section Radial Contact Ball Bearings (Type C) lies in the shape of their raceways. thin section four point contact ball bearings have two radius centers on each side of the raceway, both of which are offset from the centerline of the balls. Point Contact Ball Bearings have two radius centers on each side of the raceway, both of which are offset from the centerline of the ball. This structure makes Thin Section Four Point Contact Ball Bearings form four points of contact between the steel ball and the raceway.

Open Type Thin Section Four Point Contact Ball Bearings (Type X) increase friction resistance, improve running accuracy, and solve the size and weight problems of conventional bearings, as well as shaft and housing size and weight problems, Four Point Contact Ball Bearings are unique in that they can support radial and oil-white loads in both directions. The unique feature of four-point contact ball bearings is that they can support radial and axial loads in both directions, and their extremely thin cross-loading surfaces enable them to provide great size and weight savings for light to medium-sized applications with slow or intermittent rotations. Because a four-point contact ball bearing can usually replace two bearings, the design is much more streamlined, and the four-point contact ball bearings can be supplied with different internal preloads and clearances according to the customer’s requirements, and this can be achieved through the use of ball bearings with a larger clearance than that between the raceways of the inner and outer rings. Of course, even in the absence of external loads, the balls and raceways will deform elastically.

Bearing material: Gcr15 and SAE 440C, 9cr18 and so on.
Rolling body: ceramic ball, steel ball, etc.
